It sounds like the rear fan is good enough with your setup or you could try lowering the RPM for the top fan before removing it.

If you are overclocking then a cooler with push/pull or 2 tower/2 fan setup would be more ideal if you are trying to keep things cooler and quieter. But I would wait for the new coolers that support Ryzen 3000 and AM4 are available if you are going to change the cooler.

2 fans gives you sqrt(2) airflow (141% airflow), thus allowing you to run your fans at 70% of the speed and have the same airflow, and 2 fans at 700rpm is quieter than 1 fan at 1000rpm. performance-wise, minimal esp. as you get higher and higher airflow.

sometimes top exhausts can actually increase temps, instead of air going to the cooler, air goes to the top exhaust.

Its minimal, usually between 3-5c at most.. in general its not really worth it.

Thanks, yeah I plan to overclock the 2600 a bit and if I can get it as quiet as I can it'll be a plus for me. @alyen I never thought about that. As I don't have any immediate need for a new cooler I can wait for 3rd gen Ryzen to come out and see if there's better coolers that come out then.

Yeah that's what I thought was happening. I'll try lowering the speed of the top exhaust or unplugging the fan and test the temps out.

What you currently have is fine. Removing the top fan probably wouldn't help but it doesn't hurt to try.

What cooler did you have in mind? Push / pull can help but it might not be worth the extra money.

LL's are good if you're into their lighting options. There are otherwise cheaper rgb fans or better non-led fans in general.

@Firewrath9@WoodenMarker I was looking at the Hyper 212 Black Edition as it was around $30 and it seemed the performance was pretty good at that price. Plus it'll look great in my white H500 case.
